A few thoughts on some of the previous posts...
The airplane that landed in Craig a couple of years ago wasn't part of a local mom-and-pop operation; it was TWA.
Win, at SportsStalker, is great, but he's not really involved in the normal rental program. He's more involved with renting high-end demos. If you're willing to rent equipment just a bit away from the mountain, you can save money. Try Ski Haus, One-Stop Ski Shop, Ski and Bike Kare, and maybe even Christy Sports at Central Park.
If you can get fares into Hayden at near the same cost as flights into Denver, jump at the opportunity. I love the Denver-Steamboat drive in the summer, but the I-70 corrider and Rabbit Ears parts of the drive are things I try to avoid as much as possible in winter. Personally, I think the scenery is beautiful for the entire drive, but that's just me.
For discount tickets, pick up an application for a Steamboat Card. For a card fee of $10, there can be significant savings off daily lift ticket rates. They don't have those Steamboat Card applications in Steamboat -- only at select locations in Denver and the Front Range. Alternatively, if you'll be skiing here enough days, check out mEtickets
PinHed, I was skiing Closet and Shadows the same day as you (as well as the day before, the day after, and today!).
